Alpine ENT’s Data Breach Investigation
Alpine Ear, Nose, & Throat, P.C. (“AENT”), a medical practice based in Fort Collins, Colorado, is the latest healthcare provider to confirm a cybersecurity incident that compromised patient data. The breach was discovered on November 19, 2024, when AENT detected suspicious activity on its internal systems.
Upon identifying the threat, AENT took swift action by coordinating with its Managed Services Provider (MSP) to secure its network. The organization also hired a third-party cybersecurity firm to conduct a forensic investigation to determine the extent of the breach. The investigation confirmed that an unauthorized actor had accessed AENT’s systems and potentially acquired files containing personal information.
To determine exactly what data was exposed and who was affected, AENT initiated a comprehensive data mining process that concluded on October 9, 2025. After verifying contact information, the healthcare provider finalized its notification list and began sending letters on January 26, 2026. In total, 65,648 individuals were affected, including 10 Maine residents.
AENT states there is no evidence the data has been misused, but due to the sensitive nature of the compromised information, precautionary measures were implemented. The company has strengthened its cybersecurity defenses and is offering complimentary credit monitoring to impacted individuals.
This breach highlights the critical need for robust data security in the healthcare sector. Patients entrust medical providers with highly personal data—and when that trust is broken, legal options should be explored. Class Action U is here to help you understand your rights.
